VEHICLE-WHEEL.

Specification of Letters Patent.

Application filed January 25,1905. seen No. 242,596.

To 015E whom it may concern.-

Be it known thatI, FREDERICK J. LANCAS- TEE. a citizen of the United States, and a resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in VehicIe WheeIS, of which the following is a specification.

The object of my invention is to provide an improvement in vehicle-wheels, the novel featunes-of the invention relating more particularly to themethod of s acing a tire of soft rubber compound or ana ogous material from and interlocking it with the telly, the tire being unattached to any metallic band or its equivalent, thus securing the advantages of a pneumatic tire by the use of .a solid tire.

In the accom anying drawings, Figure 1 represents in si e elevation, partly in'longitudijial central section, a vehicle-wheel illus trating one embodiment of my invention. Fig. 2 is a cross-sectional view in the plane of the line A A of Pi 1. Fig. 3 is a view in side elevation, partially in longitudinal central section, of a vehicle-wheel, showing another embodiment of my invention; and Fig. 4 is a cross-sectional view in the plane of the line B B of Fig. 3.

The-spokes of the vehicle-wheel are re resented by 1 and the telly by 2. This tel y'is provided with alternating annular series of sockets 3 and rigid lugs 4.

The tire (denoted by 5).is composed of soft rubber compound or analogous'material and is unattached to anymetallic band-or its equivalent which would tend to impair the free yielding of the tire on its springs. The tire is provided at its inner periphery withprojections or recesses, in the present instance inwardly-extended yielding. lugs 6, which eX- tend into the sockets 3 in the fellyand overlap the outwardly-extended lugs i ofthe felly. By the use of the term projections or re cesses it is to be understood that I contemplate the formation of abutments for the interlockin engagement of the springs either,

by provi ing the tire with recesses or by providing the tire .with lugsprojecting from its springs are preferably made of spiral form, as s own, with their inner ends overlap ing to a greater or lesser degree their outer en s. The walls ofthe lugs 4 and 6 are made curved, so

as to fit the outer walls of the sprin s, and thelugs project beyond the centers oft e springs,

so as to cause the springs to have an interlocking engagement between the lugs. The outer ends of the lugs 4- are spaced a short distance from the inner walls of the flexible tire 5, and the inner ends of the lugs 6 are similarly s seed a short distance from the bottoms o the sockets 3 in the felly. This construction 'ermits the tire to be interlocked with tile folly, yet yieldingly spaced therefrom, and does away with the use of a metallic band or its equivalent for the tire, which would decrease its resiliency. This construction furthermore permits the tire to be placed upon driving-wheels as well as ordinary traction-wheels of a vehicle.

The felly 2 of the vehicle-wheel is provided.

with annular flan es 9 and 10, which overlap ,the sides of the tire 5, thus holding the tire against lateral displacement.

In the construction shown in Fi s. 1 and 2 I the arts may be assembled as fol ows: The

flexi le tire. 5, composed of rubber compound or analogous material, may be split into one or more sections. position between the flanges 9 and 10. The coil-springs are then inserted through holes 11 in the side flanges, which holes are provided with tapered wal s. A bolt having a head 12 fitted to each of the holes 11 is then inserted into position to retain the spring 7 in position, the shank 13 of the bolt rejecting through the opposite flanges and t ere being provi ed with a lock-nut 14.

In the form shown in Figs. 3 and 4 one of the side flanges of the folly is made removable, an annular series of bolts 15 being utilized for locking the flange to the felly. In

this instance a bolt 16 may bepassed through.

the centers of the coil-springs 7 to hold the removable flange in the fixed flange at this point. In this-form the flexible tire may be made in a single undivided ring.

-- While I have shown and described two embodiments of my invention, it is evident that'various other ways might be employed of attaching the tire to the is 1y. Hence I do proper position. to'the The tire is inserted into not wish to limit myself strictly to either of the forms herein set forth; but

i lhat I claim isl. The combination with a vehicle wheel telly, of an. annular series of independent springs arranged around the wheehielly, and a tire of rubber compound or analogous material having an annular series of inwardlyextended lugs overlapping the springs Whereby the tire is interlocked to and yieldingly spaced from the telly by the said springs.

2. The combination with a vehicle-wheel telly having an annular series of outwardlyextended lugs, of a tire of rubber compound or analogous material unattached to any metallic band or its equivalent and having an annular series of inwardly-extended lugs and springs engaging the lugs of the telly and tire for yieldingly spacing the tire from and inter-- looking it with the telly.

3. The combination with a vehicle-wheel telly having an annular series of outwardlyextended lugs, of a tire of rubber compound or analogous material unattached to any metallic band or its equivalent and having an annular series of inwardly-extended lugs and coil-springs interposed between each pair of alternating lugs for yieldingly spacing the tire from and interlocking it with the telly 4" The combination with a vehicle-wheel telly having alternating annular series of sockets and lugs, of a tire oi rubber compound or analogous material unattachedto any metallic band or its equivalent ar1d having an annular series of lugs extending into the said telly-sockets and springs located in the sockets engaging the tire and interposed between the saidlugs for yieldingly spacing tire from and interlocking it with the 5. The'combination with a vehicle-wheel telly having alternating annular series of sockets and lugs, of a tire having lugs extended into the said sockets and springs interposed between the lugs for 'yieldingly spacing the tire from and. interlocking'it with the telly, the said lfelly being provided with annular flanges for overlapping the sides of the tire.

6'. The combination with a vehicle-wheel telly having an. annular series of outwardlyextended rigid lugs, of a tire of rubber compound or analogous material unattached to any metallic band or its equivalent and having' an annular series of inwardly-extended yielding lugs alternating with said rigid lugs and springs interposed between the rigid and.
